"What a thousand acres of Silphiums looked like when they tickled the bellies of the buffalo is a question never again to be answered, and perhaps not even asked." -Aldo Leopold
As you know by now, the Short-eared Owl does not nest in Missouri. It uses our state as a wintering ground and nests in the plains states and up into the tundra of Alaska and Canada. It does the same in conducive habitats in South America, Europe and Asia and is even found in Hawaii. In Missouri winters, these birds of prey feed primarily on voles, mice and other small mammals but, in the summer, they expand their diets to include almost anything they can catch including arthropods, birds, reptiles and amphibians.
The Flaming Owl was the original English name given to the Short-eared Owl. This directly represented its Latin binomial of Asio flammeus, and assumedly refers to the fiery textures and colors of its plumage. I like to think that it might better represent the look of the bird when it is typically seen – in the golden warm light of the setting or rising sun.
I’ve been hunting and trying to photograph Short-eared Owls in Lincoln County, MO for nearly 10 years with mixed success. The past three years or so have been particularly challenging with lower numbers than typical, often without seeing a single owl on several outings. We hypothesize that a year or two of bad flooding in these areas adjacent to the Mississippi River have caused dramatic declines in the small rodents that these and other birds of prey need in order to spend their winters here.
Whatever the reasons, this winter (2021/2022) we are seeing incredible numbers of these long-winged beauties. Although primarily nocturnal, this species also exhibits diurnal and crepuscular habits and this is another area where we have been fortunate. I have spent close to 25 afternoons and evenings with these birds over the past six weeks, sometimes alone and sometimes with friends. On most of these days at least one or two owls were seen flying with the sun still well into the sky. This makes for excellent opportunities for observing their behaviors and working on better strategies to get the meaningful photographs we are after.
I have probably kept way too many photographs that will require purchasing new external drives much sooner than I anticipated and I have probably processed too many as well. Still, I plan on sharing many of these here over the course of the next several weeks. Hell, the season isn’t over. I’ll probably try for more before they head back to the great north for the breeding season.

I don’t usually like to discuss gear on this blog, but once in a while I think there are some things new or interesting enough to talk about, particularly when I think they may be critical for producing the best possible results. I have been wanting to test and compare the 2 latest Canon teleconverters (Canon Extender EF 1.4X III, Canon Extender EF 2X III) in a head to head test for sometime and this past weekend found me with an opportunity to do so. To be clear, this was not the optimal situation to make this test. The light was poor and the subject was probably too far away and not covering enough pixels to make a relevant comparison. But, I thought I’d give it a try.
These tests were setup as equally, but not scientifically, as possible. For these first two images, I processed as normal and tried my best to be equal in all capture and processing steps. I cropped to make the bird approximately the same size in both images, so obviously, the photo made with the 1.4X tc was enlarged more than the one made with the 2X tc. I then resized each to make them 1000 pixels on the horizontal. The purpose here was to see if there is a discernible difference in sharpness and image quality between the two. The 2X tc often gets poor reviews, but just as often gets raves by those who claim to know what they’re doing. Many claim that the better results are made by using a 1.4X tc, or native lens and cropping in post to obtain better results than those obtained by using the 2X tc for an optical zoom.

Open the two images above in separate tabs to see a roughly equal comparison. In my opinion, I was pretty pleased with the results of the 2X tc in sub-optimal conditions. Both photos are fine for sharing on the web, although the IQ would limit print size. Like I said, the conditions were poor and the bird at a great distance. However, I think I would give a slight edge to the photo made with the 2X converter. This edge might just as well be due to differences in how I processed or with changing conditions within the few minutes between captured images.
Let’s look next at the “100% crops” of both photos. This simply means that these photos were both cropped at the same dimensions (4″ x 6″) and not resized. These examples were NOT sharpened.
Focal length equivalent = 500 x 1.6 x 2.0 = 1,600mm
Focal length equivalent = 500 x 1.6 x 1.4 = 1,120mm
Again, with this comparison, I find the two very close. Either one would work well enough, but if your goal was to maximize print/display size, I would probably go with the 2X tc. I guess this has surprised me a bit. I was expecting that, under these sub-optimal conditions, the 2x tc would fall behind the supposedly sharper combination of the 500mm + 1.4X tc.
What do you think? Did I make any major blunders in my comparison or analysis? Please let me know. I do hope to make this comparison again under perfect light and optimally placed subject sometime in the future.
Miguel and I have been trying to get some better in-flight shots of the Short-eared Owls that use the wet prairies at BK Leach CA for their winter homes. Tonight, preparations and fortune came together and we wound up with a few that we can be satisfied with. The lighting wasn’t great, as the nice sunlight was blocked by heavier and heavier clouds as soon as the action began, but sometimes you take what you can get.
For the first time since junior high I did not watch a single down or minute of the NFL this season and I couldn’t be happier for it. Rape my town three times, NFL – shame on you. I’ve been pleased to get those precious free minutes back for my Sundays, several of which I found I could spend not dreading the upcoming workweek.

When the forecast showed a near perfect meteorological condition for shooting the Short-eared Owls of BK Leach, I figured this could be promising. While most other naked apes with functioning vision would be in front of the picture box and ingesting mass quantities of wings and beer, I would enjoy the warm and lightly breezy evening in my own kind of chair with friends of a different sort.

Of course there is never a sure thing. Often, when I have expected the best due to light and temperature, the owls don’t show where I set myself. On this particular day, all conditions came together and I had a super time.

I want to give huge thanks for my lovely and talented wife, Sarah, for the special help she gave me this season in getting my best to date SEOW in flight shots.

A perfect day ended in the perfect way – with a great sunset on the Lincoln Hills.
I have shared images and discussed the Short-eared Owl on a number of previous blog posts. Never did I imagine the “storm” that the “winter” of 2015/2016 was to bring. On many different trips to a few different places, I along with my partners Sarah and Steve, were fortunate to have great looks at great numbers of these fluffy fascinations in feathers. I can’t say for certain if this winter in this region was abnormal for hosting a greater than average number of SEOW, or if my observational skills have just improved, but it certainly seemed easier than in past years to find and watch these birds. I’ve just finished putting together a video with some video clips and highlight images that I wanted to share. Without further ado, here you are…
Oh, the challenges video brings to an inexperienced, unprepared and poorly equipped photographer. Throw in the fact that these birds are utterly unpredictable and it’s hard to believe I was able to capture what I did. So, I learn and take notes and hopefully improve next year.

Other than the simians, is there another species easier to anthropomorphize? Here we have cute and inquisitive SEOW, followed mere seconds later by the evil, harbinger of doom SEOW of which early writers told.

And then we have the indifferent SEOW…

Okay, I’ll stop now before they take my biologist card away from me…
Although I got a few images, I struggled mightily and missed several great opportunities at capturing SEOW in flight this season. The randomness of the encounters coupled with challenges with lighting and equipment make this a true challenge. Funnily, one of my better in-flight photographs was taken with a setting sun at the bird’s back – not the best opportunity…

The image below was taken with the sun in a better position. Notice the catch light, which suggests that the bird was up and in flight with the sun still in the sky. Something else in this photo that I noticed before is the difference in dilatation of the lit pupil compared to the pupil of the shaded eye.

Below is a flight shot from a further distance. I liked the warm light of the golden hour, painting the dead prairie vegetation in fire.

One night Steve and I were fortunate to have an owl perch close to our car well into dusk. It then left its perch and landed nearby in the vegetation. We could not tell if it was after a prey or decided to go back to bed, as it sat there for the short remainder of the day.

The final image I am sharing here is just to show off those feather-covered legs. A great adaptation for the cold climates in which these birds are found.
Wow. I’ve been looking for an evening like this for a number of years. I have heard and read that Short-eared Owls will often start their night early and often will often be up and active with several hours of day left. I have seen them before at dusk, right before sunset, but last night at B.K. Leach C.A. we had several on the move with almost two hours of light left. We were able to count a minimum of eight SEOW, but there may have been more. Immediately before sunset I was able to observe somewhere between 25-30 Northern Harriers along with the owls. It was quite a treat, listening to the Owl’s peculiar barks and screams as they were dog-fighting with the other owls and the Harriers who were looking for their spots to spend the night.
